When Lux and Trip are at their homecoming, they go behind the curtain to drink peach schnapps. Trip takes the first sip out of a full bottle. He has a small mouthful. He then hands the bottle to Lux. Check out the amount of schnapps, around half the drink has gone. Lux takes a mouthful and then hands it to Trip's friend. Take another look, the bottle is almost full again.
